Detailed Answer — How to prove you are your father’s child for inheritance in Pennsylvania
If a deceased parent left an estate and the father’s name does not appear on your birth certificate, you can still inherit under Pennsylvania law if you can establish parentage. Pennsylvania recognizes several ways to establish parentage for inheritance and probate purposes: voluntary acknowledgment, a court order establishing parentage (including results from genetic testing), or by being legitimated under state law. The most common steps are outlined below.
1. Understand the legal framework
Pennsylvania’s parentage and inheritance rules allow a child born out of wedlock to inherit if parentage is legally established. For background on how courts handle parentage issues, see the Commonwealth’s information on establishing parentage: Pennsylvania Courts — Establishing Parentage. General rules about parentage are found in the Pennsylvania Consolidated Statutes (Title 23, Parentage Act). You can review the Parentage Act on the Pennsylvania General Assembly web site: 23 Pa.C.S., Chapter 51 (Parentage). Rules about intestate succession (who inherits when someone dies without a will) are in the Decedents, Estates and Fiduciaries title: 20 Pa.C.S., Chapter 21 (Descent and Distribution).
2. Common routes to prove paternity for inheritance
- Voluntary Acknowledgement of Paternity (AOP): If the father signed an Acknowledgement of Paternity form for the birth, that document can often be used to prove parentage. If he signed after the birth but before his death, that may streamline an inheritance claim.
- DNA testing (genetic proof): A court-ordered DNA test or a private test with strict chain-of-custody procedures can provide strong evidence. If the father is deceased, DNA can often be obtained from stored tissue, medical samples, a sibling or other close relative, or from personal items, subject to court approval.
- Court action to establish parentage: File a Petition to Establish Parentage in the Court of Common Pleas (family division) or raise parentage as part of an estate (Orphans’ Court) matter. A judge can enter an order declaring you to be the child of the decedent for purposes of inheritance.
- Legitimation: Under Pennsylvania law, there are procedures to legitimate a child. A court legitimation or other statutory mechanism can create the legal parent–child relationship required for inheritance.
3. Typical step-by-step process
- Collect documents and evidence: Get your birth certificate, any Acknowledgement of Paternity, medical records, photographs, letters or cards, and statements from family members who knew of the relationship. Also look for the father’s will or probate papers if the estate is open.
- Order genetic testing if possible: Ask the court to order DNA testing if the father is alive or if biological samples exist. If he is deceased, request testing of available samples or testing of close relatives (siblings, parents, children) with a qualified lab that can provide a legal chain-of-custody report.
- File the right petition: If the estate is already in probate, file a petition in the Orphans’ Court (or the probate matter in the Court of Common Pleas) asking the court to recognize you as an heir based on parentage evidence. If no probate is open, you may first need to file a paternity action in the family division or a parentage action under Pennsylvania’s Parentage Act.
- Attend hearings and submit evidence: Present DNA reports, witness statements, and documentary evidence. The court may order additional testing, hear witnesses, and then enter an order establishing parentage if the evidence supports your claim.
- Amend the birth certificate (if needed): After you obtain a court order establishing paternity, you can use that order to request that Pennsylvania’s Department of Health amend the birth certificate to show the father’s name. See the PA Department of Health guidance on birth certificates: PA Department of Health — Birth Certificates.
4. Timing and deadlines
Time limits vary. You can often bring a parentage action even after a parent dies, but probate claims must follow the deadlines that apply to that estate (notice to creditors, filing claims, and opening of probate). Courts may also apply statutes of limitations in certain contexts. Because deadlines and procedural rules can be technical, act promptly and get legal advice to avoid losing rights.
5. Where to file and who can help
Paternity and parentage matters generally go to the Court of Common Pleas in the county where either parent or child lives (family division). Inheritance disputes about a decedent’s estate are usually handled in the Orphans’ Court or probate docket of the Court of Common Pleas where the estate was opened. If you need forms or basic procedural information, the Pennsylvania Courts website is a good starting point: https://www.pacourts.us/learn/child-support/establishing-parentage.
6. Evidence that courts find persuasive
- Admissible DNA test results with chain-of-custody documentation.
- Signed Acknowledgement of Paternity forms.
- Contemporaneous documents showing a parental relationship (letters, hospital records, affidavits from people who observed the relationship).
- Probative records showing financial support, shared residence, or the father’s recognition of the child in legal or informal records.
7. If the claim is contested
If other heirs or the estate oppose your claim, the court will weigh the evidence and may order genetic testing. Be prepared for depositions, subpoenas for records, and courtroom hearings. The judge will decide whether the evidence proves parentage by the required standard.
8. Costs and practical considerations
Expect costs for filing fees, DNA tests, expert reports, and attorney fees. If funds are limited, some courts or legal aid organizations may help, and under some circumstances the court can order DNA costs paid by the estate or the other party.

Helpful Hints
- Start gathering evidence right away: birth records, family photos, letters, and any documents that show the father recognized you.
- Use a lab that offers legal (chain-of-custody) DNA testing if you plan to submit results to a court.
- If the father is deceased, look for medical records, stored tissue samples, or DNA from close relatives (siblings or the father’s parents).
- Contact the probate court where the estate is open to learn time limits for filing an heirship claim.
- Ask the court about fee waivers or legal aid if you cannot afford testing or attorney representation.
- Get qualified legal help early—an attorney who handles family law or probate can help file the correct petitions, obtain court-ordered testing, and present evidence to an Orphans’ Court or family court.
- After you win an order establishing parentage, use that order to amend the birth certificate with the PA Department of Health and to assert inheritance rights with the estate’s personal representative.
